overclaim

overclaim is a skill for Claude Code from pyyush/goal. It costs 129 tokens per session (1,873 once invoked), scanned A, original, MIT.

A checklist that makes a coding agent describe only progress supported by current evidence.

In plain words
What is it for?
Use it before reporting progress, declaring a goal achieved, or saying that a change, test, migration, or fix is complete.
Why use it?
It reduces misleading claims such as calling untested code fixed, complete, or passing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

overclaim scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

overclaim — claim only what the evidence supports

Purpose

Autonomous and long-running work fails in a specific way: the model produces a plausible artifact and then describes it as more finished than it is. A refactor "is done" when one path is untested. Tests "pass" when they were never run this turn. A migration "matches the original" when only a proxy was checked.

overclaim is the discipline that stops this. It does not slow real work down — it converts a vague success sentence into a claim ledger where every assertion carries an explicit, honest support level. It is the gate the /goal dispatcher relies on before it will ever record status: achieved.

The rule it enforces, in one line:

You may only call something done if you verified it done — this turn, against real evidence. Everything else gets labeled, not rounded up.

When this skill runs

Run it before any of these:

  • writing status: achieved to a goal record (or calling mcp__goal__update_goal);
  • calling mcp__goal__report_progress;
  • sending the user a sentence that asserts a verifiable outcome — "done", "fixed", "implemented", "passing", "green", "works", "complete", "matches", "reproduced", "ready".

If you are about to type such a sentence and you did not run the check that proves it in the current turn, stop and run this skill.

The five support levels

Every claim you are about to make gets exactly one label.

level meaning may it count toward "achieved"?
confirmed You verified it this turn against direct evidence — ran the command and saw the result, read the file and saw the content, observed the test pass. yes
partial The main thing is done but a named sub-requirement is unverified, approximated, or out of scope. no
proxy-only You have only indirect evidence — a related test passes, a large diff exists, the code "looks right". This is not proof. no
unverified You implemented or changed something but never checked the result. no
blocked It cannot be verified with the materials available. You must say what is missing. no

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
